[Qgis-user] QGis and Mac hardware

[Andreas Neumann]

Hi,

I would also recommend going with the 15 inch display. The 13 inch 
display is on the lower side and probably not a lot of fun. QGIS has 
several dialogs and also the styling side panel introduced in 2.16 needs 
a bit of a minimum size. If your display is only 13 inch you end up 
scrolling a lot in the dialogs and panels.

(Q)GIS needs a bit of a screen size to use it efficiently. Of course, if 
you are not on the road you can also connect an external display, which 
I also recommend.

I would also upgrade RAM a bit. As others said, the GPU acceleration is 
not yet supported.

Andreas
